Copper Cable Lugs — Tin Plated Optional
High-conductivity copper cable lug, manufactured from ≥99.9% oxygen-free copper, are available with an optional tin plating for excellent weldability. They accommodate cable diameters from 1.5–500 mm² and are suitable for connecting power distribution cabinets, substations, battery storage boxes, and industrial busbars.
Key Advantages
- Low contact resistance ensures stable current transmission and reduces heat generation.
- The tin plating resists oxidation and facilitates soldering, making it suitable for humid and coastal environments.
- A variety of specifications and shoulder shapes are available for custom installation, supporting both cold press and bolt-on installation.
- Material and electrical testing are completed, and inspection certificates and test reports are available.
Description
Our copper cable lug are made of high-purity oxygen-free copper with optional tin or nickel plating to ensure low contact resistance and long-term stable operation. Designed to balance mechanical strength and electrical conductivity, they are widely used in power distribution systems, industrial motors, cable wiring, busbar connections, and power equipment maintenance.
- High Conductivity: Made with ≥99.9% oxygen-free copper, it offers low resistance and heat generation.
- Corrosion-Resistant and Weather-Resistant: Available with tin, nickel, or silver plating for resistance to oxidation and salt spray environments.
- Easy to Solder and Crimping: The tinned surface promotes faster wetting and provides a strong cold-pressed finish.
- Various Specifications: Available in cable diameters from 1.5mm² to 500mm², with various bore diameters and lengths.
- High Mechanical Strength: The thickened tube and reinforced shoulder design provide excellent pull-out resistance.

Installation and Usage Recommendations
- Select the appropriate model based on the cable cross-section and bolt diameter. Request a selection chart if necessary.
- After stripping the wire, fully insert it into the terminal barrel. Crimping with qualified cold crimping pliers or a crimping machine ensures a solid crimp without voids.
- Tin-plated terminals are preferred for outdoor or humid environments, and should be sealed with heat shrink tubing.
- When soldering is required, tin-plated terminals are preferred to prevent overheating and damage to the material.
FAQ
Q: Why choose tin-plated terminals?
A: Tin-plated terminals prevent copper oxidation, improve weldability, and reduce contact resistance, making them suitable for humid or coastal environments.
Q: How do I determine terminal size?
A: Select the model based on the cable cross-sectional area (mm²) and bolt diameter (mm). We can provide a selection chart to assist with this.
